No, your vote is not irrelevant. This year you can vote for a guy who is friends with school shooters, a guy who is breaking down barriers to reading by putting tampons into the boys bathroom. Any vote for these ones will certainly matter when one stands before the Judgement seat of the Great White Throne. You can vote for Kamala who laughs about locking up single parents of crippled children, a person who is desperate to kill babies right up to the ninth month. A person who fights for democracy by bypassing the democratic process. A person who says that those who believe that Jesus Christ is Lord and King have no place at her rallies. A vote for this person is not irrelevant, in fact if I were the prosecutor it would go a long way to showing the character of the person being tried for being a hypocrite.
Even Michelle Obama can't believe this race is even close.
By every measure Kamala has demonstrated that she is ready to drive this country into the ditch.
